lVhat I claim and desire to secure by Letters Patent is :l

1. In a tank of' the character described, including a cylindrical body having. a conical bottom, a cover` on said body having a manhole concentric with the bottom, a cover for the' manhole, concentric bearings on the bottom and manhole cover,l a shaft journaled in` said bearings, a bracket on the lower end of said shaft, an agitator blade on said bracket having a scraping edge inclined to substantially parallel the bottom, means on said shaft exterior to the tank for rotating the shaft, means i'or supplying the tank, and means for drawing elf contents of the tank at different levels, the tank having a lower opening offset froml the axis thereof for drawing o contents at tbe lowest level.

2; ln a tank of the character described including a cylindrical body having a conical betteln, a cover en said body having an opening, a lid for the opening, concentric bearings on tbe betteln and lid, a shaft rotatable in said bearings, a bracket on said shaft, an agitator blade on said brackethaving a scrapingedgc inclined to substantially parallel the bottom, mcans on said shaft exterior te the tank for rotating the shaft, means for supplying the tank, and means for drawing oft' contents of the tank at varying levels, including an outlet pipe having an opening otislet from the axis at the lowest level of the tan r.

In testimony whereof I affix my signature.
